Do these chaps have anywhere even close to a good enough view of "macro" evolution to back up this kind of claim? They're saying they believe this is what happened, now can they back up this claim with the observation of the bulk of the "evolved" progression of species? Or is this a procrustean bed into which all scenarios of "evolution" must be forced?
Do these chaps have anywhere even close to a good enough view of "macro" gravity to back up the theory of universal gravitation? The evidence, after all consists mostly of vast gaps in the intergalactic void where there is absolutely no evidence of the long range effects of gravitational attraction between galaxies.
